Vagrant 拒绝启动（远程连接断开）

Question

对网络进行一些更改后，Vagrant 拒绝启动，我得到以下信息；

$ vagrant up
default: Warning: Connection timeout. Retrying...
default: Warning: Remote connection disconnect. Retrying...
default: Warning: Remote connection disconnect. Retrying...
default: Warning: Remote connection disconnect. Retrying...
default: Warning: Remote connection disconnect. Retrying...

我试图通过重新启动服务（失败）来解决这个问题，结果出现了这个问题；

$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'ubuntu/trusty64' is up to date...
==> default: Clearing any previously set network interfaces...
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["hostonlyif", "create"]

Stderr: 0%...
Progress state: NS_ERROR_FAILURE
VBoxManage: error: Failed to create the host-only adapter
VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component HostNetworkInterface, interface IHostNetworkInterface
VBoxManage: error: Context: "int handleCreate(HandlerArg*, int, int*)" at line 66 of file VBoxManageHostonly.cpp

其他人建议重启VirtualBox服务，但同样失败；

✗ sudo "/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh" restart
Unloading VBoxDrv.kext
(kernel) Can't remove kext org.virtualbox.kext.VBoxDrv; services failed to terminate - 0xe00002c7.
Failed to unload org.virtualbox.kext.VBoxDrv - (iokit/common) unsupported function.
Error: Failed to unload VBoxDrv.kext
Fatal error: VirtualBox

Answer 1

经过大量挖掘，似乎由于 VirtualBox 进程 holding locks 导致重启命令失败。

这是通过做来解决的；

# kill all virtualbox related processes
$ ps aux | grep vbox -i | awk -F ' ' '{print $2}' | xargs

# restart virtualbox service
$ sudo "/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh" restart

# try again
$ vagrant up

这对我有用.. 确保您在 virtualbox 上启用了适配器 2
